  2. If you can obtain the package, extract it into a folder your agent can access.
  3. Paste one of the prompts below and point your agent at the source page and extracted files.
New install

I tried to install a skill package from Yavira, but the item currently does not return a direct package file. Inspect the source page and any extracted docs, then tell me what you can confirm and any manual steps still required.

Upgrade existing

I tried to upgrade a skill package from Yavira, but the item currently does not return a direct package file. Compare the source page and any extracted docs with my current installation, then summarize what changed and what manual follow-up I still need.

Skill Scanner

Scan OpenClaw skills for security issues before you install them. 341 malicious skills were found on ClawHub โ€” don't be the next victim.

Why This Exists

The ClawHub marketplace had 22-26% of skills flagged as containing vulnerabilities. Common attacks include: Credential stealers disguised as benign plugins Typosquatting (fake names similar to popular skills) Data exfiltration via hidden HTTP requests Obfuscated code hiding malicious payloads Prompt injection via SKILL.md content

Scan a local skill directory

python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/

Scan a SKILL.md file directly

python3 {baseDir}/scripts/scanner.py scan --file ./SKILL.md

Scan with verbose output

python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/ --verbose

Scan all installed skills

python3 {baseDir}/scripts/scanner.py scan-all

Scan with binary checksum verification

python3 {baseDir}/scripts/scanner.py scan --path ~/.openclaw/skills/some-skill/ --checksum checksums.json

Generate checksums for binary assets

python3 {baseDir}/scripts/scanner.py checksum --path ~/.openclaw/skills/some-skill/ -o checksums.json

Verify checksums against a manifest

python3 {baseDir}/scripts/scanner.py checksum --path ~/.openclaw/skills/some-skill/ --verify checksums.json

Output as JSON

python3 {baseDir}/scripts/scanner.py scan --path ./skill-dir/ --json

SKILL.md Analysis

Suspicious URLs (non-HTTPS, IP addresses, URL shorteners) Prompt injection patterns (hidden instructions, override attempts) Requests for credentials, API keys, or tokens Obfuscated or encoded content (base64, hex, unicode escapes)

Script Analysis

Network calls (curl, wget, requests, urllib, fetch) File system writes outside expected paths Environment variable access (credential harvesting) Shell command execution (os.system, subprocess, exec) Obfuscated strings (base64 decode, eval, exec) Data exfiltration patterns (POSTing to external URLs) Cryptocurrency wallet patterns Known malicious domains Dynamic instruction fetching (remote .md/.yaml/.json downloads) Fetch-and-execute patterns (remote code execution) Telemetry leaks (printenv, logging env vars/configs/secrets to stdout) Binary/asset risks (prebuilt executables, compiled code, library injection) Shell=True in subprocess calls (RCE risk) Path traversal patterns (directory escape via ../ sequences)

Name Analysis

Typosquatting detection (compares against known popular skills) Edit distance calculation to catch misspellings and character swaps

Binary/Asset Checksum Verification

SHA-256 checksums for all binary files (.exe, .dll, .so, .wasm, .pyc, etc.) Generate checksum manifests for trusted skill versions Verify binaries against expected checksums on update Flags unverified binaries and checksum mismatches (tampering detection)

Metadata Analysis

Excessive permission requirements Suspicious install scripts Env requirements that seem unnecessary

Risk Levels

CRITICAL โ€” Almost certainly malicious. Do NOT install. HIGH โ€” Likely malicious or extremely risky. Manual review required. MEDIUM โ€” Suspicious patterns found. Review before installing. LOW โ€” Minor concerns. Probably safe but worth checking. CLEAN โ€” No issues detected. Safe to install.

Tips

Always scan before installing ANY third-party skill Even "CLEAN" results aren't a guarantee โ€” this catches known patterns If a skill needs network access, verify the domains it contacts Cross-reference skill names with known typosquats When in doubt, read the source code yourself

Category context
